A starkly beautiful region a few kilometers east of Hell E crater, which is located on the floor of the ancient Imbrian-aged Deslandres impact structure in the lunar highlands south of Mare Nubium. Numerous small, secondary craters can be identified, including several small crater chains. Also identifiable are distinctive lineations made readily apparent by the extreme lighting, representing ejecta from a nearby impact. The NAC image shown here has not been calibrated and the pixel values were... Topics: HDTV, Lunar, Moon, LRO, Lunar Reconnaissance Orbiter, LROC, What -- Crater, What -- Lunar...

In fall of 2006, the LAT was shipped to the General Dynamics facility in Arizona for integration onto the spacecraft bus. The General Dynamics spacecraft bus provides the power, data, and pointing resources that will enable the LAT to perform its survey of the Universe. Subsequent to the mechanical integration, the command, data, and power interfaces between the instrument and the spacecraft were tested rigorously to insure the compatibility of this spaceflight hardware that had been...

Aerosols are complex particles; they can occur in nature but can also be generated by humans. Black carbon, or soot, is generated from industrial pollution, traffic, outdoor fires, and household burning of coal and biomass fuels. Soot is a product of incomplete combustion, especially of coal, diesel fuels, biofuels and outdoor biomass burning. When soot absorbs sunlight, it heats the surrounding air and reduces the amount of sunlight reaching the ground. The heated air makes the atmosphere less...
